Latest Patents

One of his latest patents is for a mode-locked thin-disk laser. This innovative pulsed solid-state thin-disk laser features an optical resonator and a solid-state laser gain medium shaped as a thin plate. The design includes a cooling surface on one of the end faces, which allows for effective cooling of the laser gain medium. The laser is equipped with a pumping source that excites the gain medium to emit electromagnetic radiation. Notably, the thin-disk laser incorporates passive mode-locking means, preferably a semiconductor saturable absorber mirror (SESAM), which enhances its performance by avoiding common issues such as thermal lensing and Q-switching instabilities. The output power of this laser is scalable, allowing for increased power without compromising performance.

Another significant patent is for a passively mode-locked optically pumped semiconductor external-cavity surface-emitting laser (OPS-EXSEL). This laser utilizes a semiconductor saturable absorber mirror (SESAM) as part of an external cavity, overcoming limitations associated with edge-emitting and electrically pumped surface-emitting lasers. The design allows for high average power and large pulse energy, with sub-picosecond pulse durations achievable through external pulse compression. The integration of band-gap engineering enables the generation of efficient pulsed laser sources across a broad range of wavelengths.
